Appiicaaon met January 22.1906. senil No. 297.115,

ATo all whom, it mug/concern,.- 'Be it known -that I, MONTGOMERY WAD- and a. resident of the' city of New York., county and AState of New York, have invented certain new and useful improvements in apparatus for forming. ilaments of me amor-A phosed cellulose or similar material in the manufacture of artificial ,silk-or like substances, of which the following is a full, clear, and complete description.

My invention relates 4to certain in1prove` ments' in the construction and arrangement of the various parts of a machine for forming iilaments .o f metamorphosed cellulose or similar substances, and has for one of its ob- -jects the providing of means' whereby .the

laments are at all times laccessible Vor within the reach of the operator.

A further object of m invention is the securing of ay complete an thorough treatment` of the filaments as they traverse the ixing bath into which the celluluose is ejected and also as they are being woundby-maintainng a circulation of the vfixing solution in the tank containing the same and by causing the filaments to traverse lthe bath in a .direction op- A further object of my inventionV is to pro# vide a means upon which the spun filaments are wound and by which they are handled in the latter steps of the process of reverting and washing which will not stain or impart an undesirable color to the filaments contained thereon and will protect the filaments from injury..

Afurtherobject of my invention is to construct a machine for spinning filaments of metamorphosed cellulose in which the bodies upon which the thread is wound as it is spun may be rotated at a constant speed without yproducing an objectionable variation yin the' diameter of the iinished thread.

A further object of my invention is to win the spun filaments in open, regular, and even courses upon a lsuitable body for holding the same.

specification, Figurel represents a plan view of the machine .provided with the improvements constituting my invention. Fig. 2 is a side elevational' view cf my Iiiachine. Fig. 3 is a sectional view through one of the tanks In the drawings forming 'apart of of my machine takn on menne 3 3, Fig. i;

Fig. 4 is an end elevational view showing the l means for imparting motion to the various ,l parts thereof and the means for circulating v the iixing liquid, the .pump-reservoir and-con-i nectio'ns .being indicated in dotted lines;

Figs. 5 and 6 are views of the pivotalsupport for the filters and the means for conducting the viscoseto the filters. Fig. 7 is `a view of ,one of the details of my invention and showing one of the supports carried by the traverse-` bar for holding the thread-guides,and Fig. '8 shows a modified form of anged ring upon which the spun' fibers are wound and the details of oneof the rollers by which said ring is sup orted and rotated. i y machine consists ofV a series of comparatively narrow tanks 1, adapted to contain a suitable fixing solution. f One end of reach'tank is connected to an auxiliary supply-trough- 2, from whichthe xjng solution is discharged-over dams -3 into the fixing-tank 1-. Extending transversely over the series of tanks are the shafts 4 5, supported in suitable journals or 'boxes 6. The shaft 4 carries at one end the tight pulley 7, by which the machine is driven, and'midwayy its ends a pulley` S, from which the motion of shaft 4 is communicated or transmitted to shaft 5 by a belt 9 and pulley 10, mounted on said 'shaft 5.

On the shafts 4 and 5 and over each tank are arranged a series of rollers 1 1, arranged to support and rotate the flanged rings 12, upon which the newly-formed iiiaments are Wound as they emerge from the fixing-bath. It is, however, fully within the scope of my invention to support the said rings directly upon said shafts, dispensingA with the rollers 11. -13 indicates a traverserod or bar also situated over thev series of tanks and adjacent the flanged rings 12 for laying the filaments Ain courses upon said rings. This traversebar is actuated from one end by a cam 14, receiving its motion from thetight pulley in a mannerto be described later in the specification. The shafts4 ,5 are arranged at such a distance apart that a considerable portion of the periphery of the flanged rings is submerged beneath the surface of the fixing liquid, asis lainly shown in Fig. 3.

On the si e of the tankscopposite to that at which the auxiliary feed-'trough and flanged rings are located are arranged a series of coni- A bined filtering andspinning heads 15, arf in Fig. l3, as it is in the beginning of the operaranged to eject the viscose or similar viscous material beneath the surface ofthe liquid in the fixingtank. .In Fig. 3 is shown an enlarged view of one of the tanks, showing clearly the relationof the #auxiliary feedtrough, the combined lfiltering and s inning heads, the rollers mounted' on the ro er-carr'ying shafts, the flanged rings, and the'traverserod, all referred to above.

The liquid is supplied tothe auxiliaryfeedtrough from the reservoir I5.1 through the pi e lflocated, referably, midway between t e ends of sai trough, and the liquid in said auxiliary feed-trough flows over the dam 3 into the fixing-tank 1. In order-to make the flow of the li uid from the auxiliary feedtrough to. the Xing-tank equal, the dams 3 are made slightly inclined in the direction of their length, the higher4 portion thereof being adj acent the supply-pipe 16, for it is evident that unless some I o'vision were made the liquid would 4flow into the 'tanks nearer the said supply-pipefl faster than it' would to thosemore remote therefrom.

On the side f the tank adjacent `the com'- bined filtering and s inning heads 1 5 are overflow-pipes 17 17, y which the level of the liquid in the tank is maintained constant. The fixingli uid flowing through the'pipe 16 'is conducted' ack to the opposite side of the machine bythe inclined trough 18, lwhich discharges into an overflow-tank '19, from which the liquid is.' pumped back through'the pipe 19', pump 570,1A .and pipe 51 to the supply tank or reservOI'lLl-,ffrom which it is again fed to the auxiliaryfeed-trough through the pipe 16. .The auxiliary feedtrough 2 and the fix-4 ing-tank 1 `-'are provided with o enings 20, normally closed, by a plug or 'ot er suitable means by which1 thetanks maybe drained or emptied through the vpipes 21 when it is desised to clean the same.

My combined spinning and filtering head consists of two`disks-58 A.59.ada ted to 'compress between them a suitable filtering material 60, the disks being clamped together by a bolt 61 passing through the center ofy each disk. One disk is rovided with a lug 28, which has an opening 27, communicating .with the interior of said disk, and with a transverse tapering hole adapted to fit through the plvt 25, which also has a pas from the pipe 22 through the pivot 25 to the; filter. To the disk 59 is attached a tube 30',

which carries at its outer end aspinheret' 30.

yBetween the filler and the fixing-tank is arranged a drip-tank 32, which discharges into a suitable collecting-tank 33 through the inclined trough 34. The drip-trough 32 is lotion, the viscose discharged through the spin- I nin -head will flow therein and be collected in t e tank 33,- and the tank 33 is so located that when the filter is taken apart for the purpose of cleaning the same anyof the viscose contained therein will fall and be col.

lected in the said trough.

Heretofore it has been necessary to impart to the spools or bobbins upon which the thread is wound as it emerges from the fixingbath a constantly-decreasing speed of rotation in order thatthe surfaceat thegpoint at which the thread is being wound may have a constant speed, since it is 'apparent' that otherwise the thread on the outer course of t-he spools would be vsmaller in diameter than that on the first or inner course. I .havepro-l vided a construction in which rings of a ecmparatively large diametervmay be em oyedvv to receive the thread, with the result t at the V rings may be rotated at aconstant angular velocity, and the difference between the surface speed ojf the first and thel last course will not be so great 4as to produce an objectionable variation in the diameter of the finished thread. So far as I am aware I am the first.

to wind the lthreads as they emerge from the setting-bath upon rings of a large diameter, which are rotated at a constantI angular velocity.

The flanged rings 12, upon which the filaments are wound, may be made by strikin up a sheet of metal into cylindrical form an then forming flanges on" either end of said cyl4` inder by spinning the metal in a directionradial to the axis of the cylinder, Aand then spinning 'the e'd es of the flanges so formed gio IOC

fback parallel with the axisof the cylinder.

The flanged rings arethen carefully enameled over their entire surface and fired to form a vitreous coating completely covering the metal, wherebythe fixing solution is prevented from comlng into contact with the metal of the flanged rings,l since the metals which would be ordinarily usedfor such purposes are readily acted upon by the fixing solutions generally employed and impart an -rio undesirable color or tinge thereto and also to Y the filaments wound thereon. In order to providefor the ready access of the fixing solution to the filaments wound upon ythe The outer ends of the flanges spun parallel `to the axis of the body` of the rlngs, as decated'in suchaposition that when'the filter is scribed, are to provide the flanges iwith a swung to the position indicated in dotted lines i suflicient surface lto engage the rollersV upon with an elastic tire or rim 36, which also has a flange fitting a ainst the flange of the bodyportion of the ro ler.

The traverse Irod or bar 13 is 'arranged adjacent one side ofthe series of flanged rings and carries adjacent the surface of each ring a support 37, which in turn is provided with a thread-guide 38. I preferably construct i the support 437 vof wood and to provide it with a clamping portion by which the threadguide is held in the support by boring through said sup ort a hole slightly smaller than t e 'shank o the thread-guide and cutting` slits 39, extendin from said hole in. opposlte directions, as lustrated in Fig. 7, since when the stem of the thread-guide is forced into .the hole the support will spring-sufficiently to permit the adjustment o said-thread-guide and will thenhold with-sufficient rigidity to 'l guide the threads to the rings. Any slight ever, be readily effected by tapping t e guide i work of the machine.

adjustment of the thread-guide ma howto bring it into a position adjacent the anged ring upon which the filament is being wound. Secured to the shaft v4, which carries the tight ulley 7, is a cone-pulley 40, which throu the belt 41 is connected and drives a secon cone-pulley 42, mounted on the counv ter-shaft 43 near the bottom of the frame- The shaft 43 alsojcarries a'pulley-44, which by belt 45 drives ulley 46, which in turn carries gear 47, W 'ch meshes with a gear 48 upon the cam-shaft 49, to which is secured thel cam 14.- Traverse-rod 13 is provided with a downwardlypulley 64, as indicated in Fig. 1.

extendin followerv 13 which en ages v the outer su ace of the cam 14-and is he d in contact therewith by any suitable means, such as a weight62', attached to the other end of the traverse-rod 13 by a chain 63, passin overa hrough the above train'of 'caring it is apparent that as the drivin -sha 4 is rotated motion is communicated to the Banged rings 12, sufpported on the rollers 1 1, secured to the sha s 4 and 5, and the cam 1.4 will be rotated, causing the traverse-rod 13 to reci rocate and to carry the thread-guides 38 bac ward andior- I have found, however', that in a traverse motion consistingmerely of the parts enumerated above,l Vit often. occurs that the number of turnsawhicli,f )ne of the flanged rings will make-in' a given time will be an exact multi- '-1 the traverse-rod will make 1n the sametime,

' shifter in the following he number'of reciprocations which face ofthe flanged rings, but will be piled up on ridges on the surface of said rin'gs. In order to obviate this, I have provided the belt 41 with a shifter 52, located between the cones 40 and 42, and I reciprocate this beltmanner.: Secured to the near end of said shifter is a link 53, connected to one end of a lever`54, pivoted, as at 54. The other end of said-lever54 is connected by a link- 55l with a stud 56 carried by a worm-wheel 56, suitably secured to the framework-of the vmachine and meshin with .al worm 57, carried bytheshaft 43. the 'shaft 43 revolves, carrying with it the worm 57, the gear 56 is rotated and in turn oscillates thelever 54, causing the belt-shifter 52 to move the belt4 41 slowly backl and forth lover the cone-pulleys 40 and 42 whereby the traverse-rod 13. will be driven at variable speeds and the building up of the thread in ridges upon the rings is absolutely prevented. y employing a series of comparatively narrow fixing-tanks and-circulating-a substantially fixed' quantity or amount of fixing solution through all the tanks froml a common feed or su ly trough I may form a large number ofp aments in a. substantially 'uniform bath and at the same time all the {ilaments maybe readily reached by an operator for the purpose of starting the spinning from: 5

any particular spinning-head or for the purpose, of attaching the filaments to the flanged rings or for the purpose of catching or repairing va broken filament.

c The o eration of my machine is as follows: Motion ein communicated to the windingrings 12 ang to the traverse-rod 13 in the manner described above and thecombined filtering and spinning heads'swung on their pivots into the position indicated in dotted lines in,4 Fig. 3,. the viscose or similar substance is forced through the pipe 22and bracket 24 to' the filter 29 and thence through the tube 30 to the spinneret 30. The viscose emerging from the spinneret 30 is allowed to drop into the tank 32 until it is flowing evenly through the spinneret, whereupon the filter is swung into the osition shown in-full lines in Fig. 3, with t e spinneret`30 beneath the surface of the liquid. The filaments are then conducted under the rod 58 to the Winding-rings 12 through the threadides 38. The fixing liquid is caused to circu ate from the feed-trough 2 over the dams into the tanks and thence through the overflow-pipes 17 and inclined troughs 18 to the tank 19 in the manner described above in the specification. It will be seen that the filaments and the bath -or tank travel in the opposite direction to that of the flow ofthe fixing liquid in the tank and a thorough and complete action of the liquidon the filaments traversing it is effected. The filaments being laid in o en courses upon the rings 12,

`which rings t emselves dip beneath the surfurther action of tie liquid upon the filaments, the filaments being in actual contact with the fixing liquid a much longer time than has hitherto been possible in other machines of this class.
